Even if they haven't installed a solar array in their backyard, a new OnStar program lets Volt drivers recharge their plug-in hybrids with renewable energy.

OnStar is working with electric power systems operator PJM Interconnection to develop technology that could give drivers a choice of the type of electricity used to recharge their Volt. The new system would let drivers establish a renewable energy preference for the Volt and help them use renewably generated electricity to recharge their cars.

PJM monitors the percentage of renewable energy available on the electrical grid, and uploads the forecast to OnStar's cloud. … Read more

DETROIT--Chevy wants the nation's youth, and it built two Hot Wheels-esque concept cars to use as bait.

The two concepts, unveiled at the 2012 North American International Auto Show, go by the names Code 130R and Tru 140S. Chevy cites the potential market of 80 million people in their '20s as the impetus for these two design studies.

The Tru 140S is intended to evoke an expensive exotic car in its styling, although its profile brings the old Pontiac Sunfire to mind. And based on the Chevy Cruze platform, with front-wheel drive and a turbocharged 1.4-liter engine, it is unlikely to provide supercar performance. … Read more

Few people are getting rich selling solar energy back to the grid, but one homeowner has made enough to pay for his Chevy Volt.

Retired nephrologist Bob Stonerock says that he used the $5,600 he's made over the last two years selling solar electricity to the Orlando Utilities Commission (OUC) for the down payment on his red 2012 Chevy Volt.

The Chevrolet Volt is an extended-range electric vehicle that can operate for the first 40 miles on electricity alone before switching on its gas-powered engine. The plug-in hybrid retails for $41,000 and leases for $350 per month. … Read more

I shouldn't have to say this, but don't try this at home.

Pro-skater-cum-stunt-driver Rob Dyrdek became the first person to ever kickflip a car at a skateboarding-themed event at Six Flags Magic Mountain in Valencia, Calif.

In the world of skateboarding, a kickflip involves the leaping into the air while simultaneously flipping the board through a 360-degree barrel roll beneath you and, of course, landing safely. In the world of automotive stunt driving, a kickflip involves driving a stunt-prepped Chevrolet Sonic hatchback over a corkscrew ramp at high speed, then praying to your deity of choice as the car flies over a comically sized skateboard prop. I won't spoil much more of the video embedded below, but suffice it to say that even Dyrdek looks surprised at the end of this stunt.… Read more

In its annual list, Wards Auto lauds what its editors perceive as the 10 best engines powering cars today.

The 2011 Ward's 10 best engines list pays homage to electrification, including both the mixed gas and electric system driving the Chevy Volt, and the pure electric motor in the Nissan Leaf. One diesel also made the list, Volkswagen's TDI. Among the gasoline engines, most feature forced induction. Direct injection also makes an appearance. But big displacement has its place, as seen in the 5-liter V-8s from Ford and Hyundai.… Read more

General Motors isn't just interested in building energy-efficient vehicles; the company now says its Lansing Delta Township Assembly Plant is the company's first U.S. facility to become Energy Star certified. This means the plant has met strict energy performance levels set by the EPA from 2010 to 2011.

The Michigan plant, which builds the Buick Enclave, GMC Acadia, and Chevrolet Traverse, was designed to meet the optimum energy efficiency in heating, ventilation, and air conditioning without using steam, the company said in a press release.

The plant, which opened in 2006, has energy and water conservation features … Read more

It's going to take more than a couple of battery fires to shake the confidence of most current Volt owners--so far only 24 people have taken General Motors up on its offer to buy back their extended range electric vehicles.

The Volt is being investigated by the National Highway Transportation and Safety Administration because of fires that started in the liquid cooled lithium-ion battery three weeks after side-impact crash tests were performed by the organization. Proper post-crash safety protocols were not followed by NHTSA engineers, which requires the Volt's battery to be drained of power until repairs are … Read more
